Magic Window IIe by William H. Depew, from ARTSCI, Inc. 1984. Later followed up by Magic Window II.
From the simplest to the most sophisticated, any word processing system is basically just an electronic device for making marks on paper. One measurement of the ease of using a word prqcessor is its "transparency"-the similarity between what appears on the screen and what is printed as final copy. From this standpoint, Magic Window, written by Gary Shannon with revision and documentation by Bill Depew, may be the best word processing system available for the standard 4O-column Apple II computer.
The "virtuality" (to borrow a term from Ted Nelson) of Magic Window places you behind a window looking at a seemingly gigantic sheet of paper-say 24" by 36". You are at the keyboard of an enormously powerful typewriter, with the ability to deposit any ASCII character anywhere on this sheet in proportionately huge letters. You control the operation through the keys on the keyboard (most of them usable in two different ways), a main control menu, and subsidiary menus used for job formatting, filing, printing, and system configuration.
One unusual feature of Magic Window is that the cursor never moves; it stays right in the middle of the screen. Instead, the "paper" moves under it, just as it does on most typewriters. Any portion of the "sheet" (within the margins you have set) can be moved under the cursor. The cursor is non-destructive; it can be moved over existing text without erasing it. Text entry is similar to other word processing systems. A carriage return is required only at the end of a paragraph. If you make a mistake, just backspace and type over it. Tabs can be set and cleared as on a typewriter, with one very handy difference -you can tab either forward or backward.
